Based on Patrick Dennis' novel House Party, this series ran for one season on ABC. The premise was that the Pruitts were broke, but because of their status and position, they were allowed by the IRS to keep their home and maintain the facade of wealth in order to protect the local economy. Behind closed doors, however, they had to maintain the house themselves, leading to many jokes having to do with Phyllis' less than stellar homemaking skills.
